Which parameters are used to calculate the magnitude rating of an offense?
B
Explanation:
The magnitude rating of an offense in IBM Security QRadar SIEM V7.5 is calculated based on three
key parameters: severity, relevance, and credibility. Severity indicates the level of threat, relevance
determines the offense's impact on the network, and credibility reflects the integrity of the offense
as determined by the credibility rating configured in the log source. This combination of factors helps
prioritize offenses and guide analysts on which ones to investigate first.
Reports can be generated by using which file formats in QRadar?
A
Explanation:
QRadar supports generating reports in various file formats, including PDF, HTML, XML, and XLS.
These formats provide flexibility in how reports are viewed and shared, catering to different needs
and preferences for report presentation and analysis.
The Use Case Manager app has an option to see MITRE heat map.
Which two (2) factors are responsible for the different colors in MITRE heat map?
C, D
Explanation:
The MITRE heat map in the Use Case Manager app within QRadar uses several factors to determine
the colors displayed, among which the number of rules mapped to MITRE ATT&CK tactics and
techniques and the level of mapping confidence are crucial. These factors help visualize the coverage
and reliability of rule mappings against the comprehensive MITRE ATT&CK framework, aiding in the
identification of potential gaps or areas for improvement in threat detection capabilities.
In QRadar. what do event rules test against?
B
Explanation:
Event rules in QRadar test against incoming log source data processed in real time by the QRadar
Event Processor. This real-time processing enables QRadar to analyze and respond to security events
as they occur, enhancing the system's ability to detect and mitigate threats promptly.
What two (2) guidelines should you follow when you define your network hierarchy?
B, E
Explanation:
When defining the network hierarchy in QRadar, it is recommended to organize systems and
networks by role or similar traffic patterns to differentiate network behavior effectively. Additionally,
it is advised not to configure a network group with more than 15 objects to avoid difficulties in
viewing detailed information for each object and to ensure efficient management of network groups.
Create a list that stores Username as the first key. Source IP as the second key with an assigned cidr
data type, and Source Port as the value.
The example above refers to what kind of reference data collections?
C
Explanation:
The example provided refers to a "Reference table," which is a type of reference data collection in
QRadar that can store complex structured data. A reference table allows for multiple keys and values,
supporting the storage of data like Usernames, Source IPs with a specific data type (e.g., cidr for IP
addresses), and Source Ports as values.
What type of custom property should be used when an analyst wants to combine extraction-based
URLs, virus names, and secondary user names into a single property?
A
Explanation:
When an analyst wants to combine multiple extraction and calculation-based properties into a single
property, such as URLs, virus names, and secondary user names, an AQL-based property should be
used. AQL (Ariel Query Language)-based properties allow for the aggregation of diverse data types
into a unified custom property, facilitating more flexible and comprehensive data analysis within
QRadar.
What happens when you select "False Positive" from the right-click menu in the Log Activity tab?
A
Explanation:
Selecting "False Positive" from the right-click menu in the Log Activity tab opens a window that
enables users to tune out events that are known to be false positives, preventing them from
generating offenses. This feature is crucial for minimizing noise and focusing on genuine threats,
thereby enhancing the efficiency of threat detection and response processes within QRadar.
Which statement regarding saved event search criteria is true?
B
Explanation:
In QRadar, when you save search criteria, especially on the Offenses tab, the configured search
criteria are retained for future use and do not expire. This permanence ensures that users can quickly
access and reuse their preferred search configurations, thereby streamlining the process of
monitoring and investigating offenses over time.
Which two (2) aggregation types ate available for the pie chart in the Pulse app?
B, C
Explanation:
For pie charts in the Pulse app of QRadar, the available aggregation types include "Total" and
"Average." These aggregation types allow for the representation of data in a manner that
summarizes the total sum of the data points or their average value, respectively, providing insightful
and concise visualizations of the data within the Pulse app dashboards. This information is implied
from the general capabilities of dashboard items in QRadar, as detailed in the provided
documentation, which typically includes such aggregation options for data visualization.
